In 1993, the New England Journal of Medicine (NEJM) published landmark research from Loma Linda University showing the heart protective quality of walnuts. In the two decades since, 91 studies and counting, worldwide, have linked numerous potential health benefits from walnuts in the areas of heart health, diabetes, weight management and cognitive function.

Recent research published online by the Journal of Nutrition, found an inverse relationship between walnut consumption and risk of type 2 diabetes in two large prospective cohorts of U.S. women: the Nurses' Health Study (NHS) and NHS II.

A meta-analysis published in the recent issue of the American Journal of Clinical Nutrition evaluates how the plant-based omega-3 fatty acid alpha-linolenic acid (ALA) offers protective effects on cardiovascular diseases (CVD).

Research published in the recent issue of Biology of Reproduction Papers-in-Press reports that 75 grams (approximately 2.5 ounces) of walnuts consumed per day improved sperm vitality, motility, and morphology (normal forms) in a group of healthy young men between 21-35 years of age.
